Notes:
5. Dropout voltage is the voltage difference between the input and the output at which the output voltage drops 2% below its nominal value.
6. Quiescent current defined here is the difference in current between the input and the output.
7. Short circuit current is measured with VOUT pulled to GND.
8. This specification is guaranteed by design.
9. To make sure lowest environment noise minimizes the influence on noise measurement.
10. AP7346 is available for built-in discharge.
11. Potential multiple grades based on following output voltage accuracy.
